It may be easier to just put some cardboard in front of your radiator. This will cause the engine to warm up faster as the coolant is unable to cool as well. I used it in a Geo Metro & it worked fine. Much safer, just make sure you don’t overheat the engine.

Darn it
I just entered a long and comprehensive comment, but when I tried to send it my Internet Explorer crashed.
Did it come though or is it lost and I have to do it again?

Just set yourself on fire, and then jump into the car and speed away. Something like the Ghost Rider with a VW bug.

you are a genius dunkoriffic… actually whoever thought of that… but thank you.

once i get access to a mig (or get around to fixing mine, if possible) i’m going to weld a box around the tailpipe with a couple hose fittings on it, and hook that up to a y-mixer, one side from the hotbox and the other to ambient air, add a thermistor to the outlet to adjust the mix ratio so i don’t get air hotter than 120 or so (thats what water heaters are set to to prevent burns) and add that into the air system. thats a great idea!

I think we’re all looking at the problem the wrong way. Under the hood there is an item that warms up straightaway – the engine exhaust pipe. Put your hand on it if you don’t believe me!
Air cooled Porsche cars have a hot box – a steel box that fits around the top of the exhaust where it meets the engine. Air is blown over this and it heats up instantly. Not that I’ve got a porsche, the 1970 440 cu inch roadrunner in my garage warms up PDQ without the aid of a heater anyway!

why didn't he just use a blow dryer? they are designed to blow air over the coils, most likely have a thermal cutoff switch to keep the air from getting too hot (like say, a temperature you could make toast with) and you could keep the entire "barrel" assembly (think of the blow dryer in gun terms) because the coils are already mounted and electrically insulated from each other

youre using a flamethrower to do the job of a flyswatter. a flamethrower has more power, but a flyswatter won't burn your house down. choose the right tool for the job

used a propane space heater (the ones that mount on the little bottle you use camping) to heat my truck when it was -5f once

I had a 79 Honda AccordLX that had from the factory electric heat in the vents. It also shut off when the incoming air was warm enough.

Also had a coworker that made something like this 15 years ago when he heard me talking about my Honda. What he did, though, was to use little 12V heating elements (kinda like 4"x8" heating pads) that came out of military battery packs. He wired them to the car's 12V system with a dashboard switch and put a thermal switch in the vent before the heating pads to shut them off when the incoming air got to something like 100 degrees.

Worked great! The heating elements could not get hot enough to damage anything since they were designed to go up against batteries in a plastic enclosure, but got plenty warm enough to get his big old Ford LTD warm right away in Michigan winters.

I dunno why the other parts were deemed “un-needed”. The thing would make a rather good bagel toaster for the drive in to work.

peter, the voltage doubler is to increase the cfm of the fan. it does not need 4 amps.

Hot, fresh, on the go toast.

Now THAT'S engineering!
